import std.algorithm;
import std.array;

class A {
    B[] b;
}

class B {}

void main() {
    A a;

    a.b = a.b.map!(b => b)().array();
}

This code segfault in invariant._d_invariant with dmd 2.060 . This ork fine
with (B b) { return b; } as delegate.

The variable a is class, and initialized with null, then this code never works.

Ooops, it seems I failed to reduce the bug to a simple case (I actually
introduced a new problem of my own, you are right). And if I initialize a, the
segfault don't occur. This bug report is invalid, I'll create a new one with
some help of dustmite.
